One of the many treasured pieces is a Victor Edelstein ink-blue velvet gown, which the Princess of Wales famously wore at the White House when she danced with John Travolta.

Diana once resided in Kensington Palace and often stopped to greet the gardeners. In addition to seeing the suits, dresses, florals and colorful prints she was known for, a special white garden will be planted in her honor and inspired by her style.

The royal website said the exhibit will "trace the evolution of the Princess’s style, from the demure, romantic outfits of her first public appearances, to the glamour, elegance and confidence of her later life. From her earliest royal engagements, everything Diana wore was closely scrutinized, and the exhibition will explore how she navigated her unique position in the public eye: learning to use her image to engage and inspire people, and to champion the causes she cared about."

Tickets to the Princess Diana exhibit will be included in the palace admission price and will be available to buy online starting Dec. 1.
